Your sleeping position depends on back pain while sleeping. If you sleep on your back, try placing a pillow under your knees while you snooze. This will allow for proper alignment of the spine. If you sleep on your stomach, a pillow under your lower abdomen can help, while those who sleep on their side should tuck the pillow between their knees.

Try a New Mattress.Your bed may be to blame for your aching back. In fact, 63 percent of people say that their back pain improved after switching to a new mattress. Look for a medium-firm or firm mattress (the super cushy ones may feel great at first, but they are not back-friendly). Many companies allow you to test drive a mattress for a few weeks before you’re obligated to keep it, which is a good method for finding one that works for you. If a new mattress isn’t in the cards, adding plywood supports under the mattress may help.

Use a small flat pillow for the head. If the pillow may lift head high then it can cause neck and back pain.
